Press2ToContinue writes "Scientists have found a relatively straightforward way to persuade the cells discarded in human urine to turn into valuable neurons. The technique, described online in a study in Nature Methods this week (abstract), does not involve embryonic stem cells. These come with serious drawbacks when transplanted, such as the risk of developing tumors. Instead, the method uses ordinary cells present in urine, and transforms them into neural progenitor cells — the precursors of brain cells. Researchers routinely reprogram cultured skin and blood cells into induced pluripotent stem cells, which can go on to form any cell in the body. But urine is a much more accessible source."

It's today's.Samson: What group is it?Grimshaw: What groups are there?Samson: There's 'A',--Grimshaw: It's 'A'.Samson: (sniffs blood) Wait a moment. It's mine. This blood is mine! What are you doing with it?Grimshaw: I found it.Samson: You found it?! You stole it out of my body, didn't you?Grimshaw: No.Samson: No wonder I'm feeling off-colour.

You stole it.Grimshaw: Never.Samson: Give it back to me.Grimshaw: All right...but only if I can give urine.Samson: Get in the queue...
